Quadraphonic sound Puns

Title

I have a Pioneer QX-747. I love the looks of it and my novice ears thinks it sounds good despite it needing a bit of work / service. I currently don't have any interest in using it in 4-channel mode. I am on the fence about paying to restore it versus putting my money towards a vintage 2-channel receiver of similar value that does not need to be restored.

One positive about using a quadraphonic in 2-channel mode is the power, which goes from 20 watts per channel in 4-channel mode, to 65 watts in 2-channel. However, given that the receiver was built around playing quadraphonic, I'm wondering if there's any sort of compromise when using it in 2-channel mode?

My guess is that the sound quality depends on the quality of the receiver, not whether it's quad or stereo, but I thought I'd ask.

Tell me folks

I’m getting my first audio set up

Do I need to invest in quad versions of Zappa vinyl in your opinion, and does that sound good with a nice set of 2 channel speakers and standard rear speakers for Dolby surround? Advice much appreciated, my FZ vinyl collection is about to grow immensely but after learning about quadraphonic recording I’m very intrigued.

Edit: after I posted this I did learn about this company-http://involveaudio.com/product/surround-master-v2/

They make a digital decoder that one can hook a conventional stereo turntable to, and have a SQ Quad vinyl record decoded into a 5.1 home theatre system.

Therefore I’m guessing it’s not feasible to just have Quad vinyls playable on a standard turntable much less sound right. I still think this could be an interesting discussion. I was originally looking at buying Apostrophe on Quad

Did anyone else notice the amount of extra rigs in the rafters? And during CCT the quad panning of the audio? This is new right? I might be wrong with the terms, any help understanding this would be appreciated.

I am exploring multichannel capabilities of SC.

May I know what types of file formats Quadraphonic sounds can be exported to?

Can SC export multichannel formats?
Also what DAWs can you export quadraphonic files?

Thank you very much~

They're really the best for listening to jazzzzzz.

Just finished this track. I'm obsessing over valhalla shimmer again...

As I finally ordered my remaining three monitors for my 5.1, and with the inclusion of a digital surround processor, I'm wondering if I can utilize this setup to play quadraphonic vinyl, 8-track or open reel.

Do you need a special turntable or reel to reel to playback quadraphonic media or is it some witchcraft using a specific preamp? The digital processor I have has coaxial, optical and line in with line out R/L/C/SR/SL/LFE. My thought is if there is a special quadraphonic preamp/amp/receiver that I have to use that has 4 line outputs, I could simply use the line input on my processor to route it to the appropriate speakers.

Here's the current equipment situation:

• 5x M-Audio BX5a (R/L/C/SR/SL)
• 1x M-Audio SBX10 (LFE)
• Technics SH-AC500D (digital surround processor/preamp)
• Blu-ray player
• TV (with no HDMI/optical output)
• Fosmon HD1996 (HDMI switch with optical, coaxial and line output)

But I don't know where to begin finding quadraphonic equipment, media, or if it's even worth it. What do y'all think? Is this plausible? Is quadraphonic stuff so esoteric or prohibitively expensive it's not worth it?

Hello fellow audio engineers/enthusiastics,

I've had this thought for a while and I've been pondering how to achieve this kind of acoustic effect. Is it possible using binaural/stereo recordings (using the same signal for the rear speakers) and how is the technical side of things; ie. is it possible only by using an SACD.

I've noticed it is possible using headphones but it doesn't leave the mix mono/stereo compatible. M/S EQing is something I experimented with, as well as analyzing the tracks with Cubase Multiscope. The 6to2 plugin has some nice features to it yet I lack the proper sound system and motivation to test the recordings live.

I tried making an X/Y controlled Instrument Rack in Ableton Live using M/S, delay and reverb, but I ran into phase correlation issues. Utility-plugin and run everything into a single mono send channel maybe and add that to the stereo signal?

I have two sets of speakers, I have one set up through the rear output that seems to work fine but I can't get the front sound to come out of the front two speakers correctly. I have tried jacking in to both center as well as side outputs with no luck. Tried a few different configurations in the settings and I just can't seem to figure it out. Any help would be much appreciated thanks!

Edit: Got it. With the suggestion from /u/Sohonny I jacked the "Front" trs into the L-out of the port and the fronts started working. Thanks for looking.

I understand how the needle reads the bumps and grooves and how they are amplified through a stereo system. I do not understand how that needle can produce anything other than a mono sound. How do they play the multiple tracks and separate them with only one input?

Do you have two unused monitors and an audio interface with two unused outs? Do you want to play around with quadraphonic sound, but mix in stereo? Here's how to do it.

Setup screenshot.

In this setup, I have Outs 1 & 2 as the main L and R outs and 3 & 4 as the rear L and R outs. I've put a dummy stereo instrument in the arrange area, EFM1, just for illustration.

1. Open the preferences and open I/O assignments -> Output. You need to switch through the options until you disable all but Left, Right, L.Surround, and R.Surround, as in the screenshot. If you don't, you will get audio bleeding into channels that you don't want. I leave it on "Quadraphonic", but I'm not sure if it matters.
2. Choose a useful ordering of the channels under Display -> Mixer. I use the "Internal" ordering.
3. Create two aux channel strips with "surround" output. I call these "Front Spk" and "Rear Spk". These are stereo inputs that will send audio to the front and rear speakers, respectively.
4. Double-click the surround panning knobs to open the "surround panner" on "Front Spk" and "Rear Spk". Disable the center on both and disable the rear on "Front Spk" and the front on "Rear Spk". Set "Angle", "Diversity", and "Spread" as in the screenshot. This will ensure that for example, the left front aux carries all and only the audio going to the left front speaker.
5. Create a stereo virtual instrument (or audio) with no output. Create two sends, post-pan, to "Front Spk" and "Rear Spk" channel strips. The amount you send will determine respective front-rear balances. You will want to play with the send amount and L-R balance with each instrument or audio to make things interesting.
6. Create an aux stereo channel strip, "Stereo Mix". Send full levels, post-pan, from "Front Spk" and "Rear Spk", to "Stereo Mix". Choose a free output on your audio interface to send "Stereo Mix". I chose 5-6. This will create a new output.

I think I've covered everything here. If you have done it right, then sending an equally-L-R signal through the instrument will produce 4 equal bars in "Quad Out" (I've renamed the master this) and two equal bars in "Stereo Out". You can mute "Stereo Out" without affecting anything else, but muting the master naturally mutes everything.

These details are for Logic 9, but I don't see why they wouldn't still work on Logic X.

Let me pile on some disclaimers here: If you are mixing a set piece for

Hallo, I have a uni project wherein my plan is to create an immersive pod/room surrounded by blackout curtains and with quadraphonic surround sound, and a slow moving liquidy projection. I am looking for alternative ways to utilise a projector to bring more dimension to the installation, rather than just having the video playing on a large wall or screen.

Does anybody have any experience, or ideas, for how I could go about this? I have been looking into using fog screens that can be walked through and touched, disrupting the patterns in the image with the swirling fog, but think it might be too expensive or complex.

I was also thinking that maybe some kind of near-transparent fabric could be used, possibly cut into hundreds of thin strips and hanging vertically, which might make it appear three dimensional while still being able to be walked through, but I have never experimented with a projector like this and am unsure if it would work.

Any thoughts? Throw anything at me! I am essentially trying to make a bootleg hologram here, which unfortunately mostly exists in sci-fi.

Much love xoxo

Do your worst!

Building home studio. Is it better to have stereo or a quadraphonic sound system for mixing and listening.
